Borislav,

I still think you need the check for UC here.  When an UC occurs and
mce_panic() is called the output will include:

[Hardware Error]:  Run the above through 'mcelog --ascii' to decode.

potentially many, many times.  The problem still is that there is no
output to decode (in the default case).
